Command line parsing module

< ^ > P N |<>| ^ _>< --- | ~ ...Help

Thanks for the answers to my previous questions.  
Now, some more newbie questions...

Is there...

1) any module to simplify command-line parsing?
Ideally, something like Perl's Getopt::Declare.

3) any module to deal with either quicktime, mpeg or avi files (mainly play them)?

4) any 3D classes ( Vector, Matrix, etc)?

5) any module for secure shell, like Perl's Net::SSH?
